Abstract (en)
[origin: WO2022218869A1] Prepolymerized catalyst component for the polymerization of olefins comprising comprising (i) a solid catalyst component comprising Ti, Mg and an internal donor mixture (IDM) comprising from 15 to 75% of 1,3-diethers and from 25 to 85% of succinates based on the total amount of 1,3-diethers and succinates, and (ii) an amount of an ethylene polymer ranging from 0.1 up to 3g per g of said solid catalyst component (i), said pre-polymerized catalyst component being characterized by an intrinsic viscosity [η] in tetraline at 135°C ranging from 2.5 to 5.20 dl/g.
